    Took me a while to realize that Caliber is roughly inch/100. Once I did I no longer needed to memorize them.

      I don’t understand. A 5.56mm round has a .223 bullet. .223 is the caliber and is in inches already, no math required. .223 / 100 =0.00223 which isn’t particularly useful.

        Their math was flawed, but I’m not really sure how to explain the math part better. I get what they were going for, though.

        It’s closer to decimal divisions of an inch, so a .223 caliber bullet would be a hair shy of a quarter of an inch (.25) wide.

        Edit: just realized you had the second part of that already
